Ensuring your card details remain secure
Please note, to ensure that your card details remain secure, you will only be able to make online payments if you have higher than Internet Explorer 5.5 or equivalent web browser installed on your PC. New or recent web browsers support Secure Socket Layer (SSL) technology, which is an industry standard for internet payments. This means all of your personal and card details are protected using 128 bit encryption when your details are transmitted over the Internet. This makes it virtually impossible for anyone else to discover and use your details.
